Nick Williams Billet Aluminum 103mm Drive-By-Wire Throttle Body
This redesigned version replaces the previous 102mm boosted & non-boosted versions.
Nick Williams Performance drive-by-wire throttle bodies are CNC precision-machined from billet aluminum to meet the demands for increased airflow on the drive-by-wire LSX performance engines. The 103mm throttle bodies require an aftermarket intake to fit the larger diameter throttle blade. They use a 6-pin late model connector that works with late model wiring harnesses. Tuning is required for installation; and the Nick Williams Performance drive-by-wire throttle bodies come complete with stepper motor and electronics installed—no need to disassemble your factory throttle body.
